JAMES S. CROOKER, OF NEXVARK, NEV JERSEY.

SEWING-MACHINE SHUTTLE-CARRIER.

SPECIFICATION forming part of Letters Patent No. 306,135, dated October'7, 1884.

Application filed August 8, 1883. (No model.)

To all whom it may concern:

Be it known that I, J AMEs S. CROCKER, a citizen of the United States,residing at N ewark, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in ScwingMachineShuttle-Oarricrs; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being bad to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specificatioiiiThis invention relates to certain improvements in that class ofsewing-machines, including those commonly known as the Domestic, NewHome, New York, &c., having a vibrating lever arranged beneath a slottedtable and adapted to receive a cylindrical shuttle and actuate the sameto a reciprocal movement, said shuttle in said movement passing througha loop made in the thread by the needle.

The object of the invention is to prevent or reduce the noise occasionedby the shuttle when reversing its course, striking the heel ofthecarrier, and at the same time to enable an operator on said machineto raise the shuttle withincreased ease and facility from saidreciprocating carrier through the slot or opening in the table with apeculiar movement. (Illustrated by Figures 5 and 6.) Heretofore, toraise the shuttle, it has been necessary in most machines of this class,and especially those particularized, to insert the finger -nail betweenthe heel of the carrier and that of the shuttle. This process wasoftentimes vexatious, in that the shuttle was apt to slip from the handbefore it was fairly caught. It is true that heretofore lifting deviceshave been provided to throw or raise the shuttle from its carrier. Theydo not, however,producethepeculiar results attained by my improvementsto wit, the prevention or reduction of the noise occasioned by theshuttle striking the heelpiece of the carrier when the carrier in itsvibratory movements changes from an action in one direction to a reverseaction, and with the same mechanism to render it possible for theoperator to throw the heel of the shuttle upward toward the slot oropening in the mawill be hereinafter set forth, and finally embodied inthe clauses of the claim.

Referring to the accompanying two sheets of drawings, in which similarletters of refer-' ence indicate like parts in each of the severalfigures, Fig. 1 is a plan of a portion of a shuttle-carrier adapted toreceive a cylindrical shuttle, and having a lever fulcrumed on the heelthereof engaging with said shuttle to throw the heel of the latterupward. Fig. 2 is a side elevation of the shuttle-carrier with theshuttle removed and the seat of the lever raised. Fig. 3 is a secondside elevation with the shuttle in place. Fig. at is a perspective viewof a portion of the carrier, more clearly illustrating the heel-piecelever. Fig. 5, Sheet 2, illustrates the slotted bed-plate or table ofthe sewing-machine, having the shuttle-lever arranged thereunder; andFig. 6 illustrates the peculiar process of extracting theshuttle.

In carrying-out the invention, the table or bed-plate G is provided witha transverse depression, H, and slot I, adapted to be covered by slidingplates arranged in said depression and lying flush with the plate G,allin the usual manner. Beneath said plate G is arranged a vibratinglever, the head or carrying extremity a of which vibrates in a pathcorresponding with the slot, so that the shuttle can be withdrawn at anypoint therethrough. The shuttle-lever is divided into the body portionct and shuttle-carrying portion a, the latter of which parts is providedwith a horn to receive the pointed extremity of the shuttle and a heel,d, which is bent or formed at an angle to the body of thelever andreceives the abutting end or heel of the shuttle. The heel of theshuttle-carrying portion of the lever a is split substantially as shown,and into it alever, 1), is fitted to engage with the shuttle and raisethe same into catching engagement with the operators lever-depressingfinger. Of said lever Z) the seat Z) enters beneath the shuttle andraises the same, the said seat lying approximately parallel with thebody of the carrier. ed to pass intoarecess, g, in the carrier a, Fig.

The extremity of the portion 1) is adapt- 41, so that the thread in itspassage between the shuttle and carrier or lever will not catch uponsaid lever, all as willbe understood. The portion 1/, which is bent atan angle to the fulcrunied portion of the lever b, to form a cushion toprevent noise in the longitudinal movement of the shuttle, is slightlyconcaved, as shown in Figs. 2, 3, and 4, to prevent the shuttle frombinding when the same is being raised. The portion b of the lever isadapted to be depressed when the operator rests the extremity of hisfinger thereon, the weight of the finger being sufficient to raise theshuttle.

The operation of the device is substantially as follows: V hen theoperator, reaching from the front of the machine in the directionindicated by the arrow, rests a depressing-finger on the finger-piece b,as shown in Fig. 6, said finger-piece is more or less depressed, whilethe seat portion of the lever throws the shuttle up, so that the heel ofthe shuttle strikes the ball of the finger. A back movement of thefinger draws said shuttle, so that the remaining fingers of the hand mayreadily grasp the same and lift it through the opening I. The motion ofthe finger described is, in practice, a simple downward and backwardcurve of the finger, such as no other device of which I am aware wouldallow.

I am aware that changes may be made in the form of the parts withoutdeparting from the spirit of the invention, which, having described, Inow set forthin the following clauses of the claim.

\Vhat I claim as new is 1, In asewing-niachine, the head oftheshnttie-carrying portion of the lever provided with bent extremities,upon one of which a lever, b, is fulcrumed, said lever having the fingerpiece 1/, the cushion 1/, adapted to receive the longitudinal motion ofthe shuttle when the motion of the lever changes, and the seat b, allsaid parts being arranged and operating substantially as herein setforth and shown.

2. In a sewing-machine, the head of the shuttle-lever a, provided withbent extremities to engage with the ends of the cylindrical shuttle, oneof which extremities has a lever, Z), fulcruined thereon, said leverhaving the finger-piece b, the concaved cushion b, and the seat I), allsubstantially as set forth.

The combination, with the slitted heelpiece of the shuttle-carrier, ofthe lever 1), arranged thereon, having the seat portion 1) and bentextremity 1)", arranged in a recess of the shuttle-carrier,substantially as set forth.

4. The combination, with the shuttle carrier having the heel d, of alever fulcrulned on said heel, and having the seat I) and concavity b,substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this6th day of August, 1883.
